WhatRuns is a browser-based profiler that identifies the technologies behind a website and alerts users to stack changes.
WhatRuns identifies the technologies, frameworks, analytics tools and third-party services running on a website, presenting the result as a readable profile of that site's stack. Its browser extension surfaces the same profile inline while a user browses.
Users follow individual websites and receive notifications when a tracked site starts or stops using a technology, which makes the service usable both as a point-in-time profiler and as a lightweight change monitor for named domains.
